摘 要: | 以引江济淮试验工程为依托,开展砂岩与泥岩的崩解特性试验研究。通过静态烘干-浸水崩解试验,研究不同风化程度的软岩在干湿循环作用下的崩解性状,同时进行耐崩解试验以及点荷载强度试验,揭示崩解性与强度、失水率的相关变化规律。试验表明:干湿循环作用和风化作用均会减弱岩石耐崩解能力;风化岩石的耐崩解指数与干燥岩石点荷载强度成正相关,与岩石的失水率成线性负相关;岩石的耐崩解性与岩石结构类型关系密切。

Abstract: | Experimental study on the disintegration characteristics of sandstone and mudstone is investigated based on the diversion project of water from Yangtze to Huaihe River. The disintegration characteristics of soft rock with different weathering degree under drying and wetting cycles are studied by drying-immersion static rock slaking test. At the same time, the rock slake-durability tests and point load strength test are carried out to reveal the correlation law between disintegration and strength, the loss of moisture. The results show that the effect of drying and wetting cycles and weathering could weaken the rock slake-durability; and the rock slake-durability index increases approximately linear with the point load strength and decreases approximately linear with the loss of moisture of the rock. The slakedurability of rocks is related to rock structure types. |
